The containers are made up of a number of _buckets_, each of which can contain any number of elements. For example, the following diagram shows a `xref:reference/unordered_set.adoc#unordered_set[boost::unordered_set]` with 7 buckets containing 5 elements, `A`, `B`, `C`, `D` and `E` (this is just for illustration, containers will typically have more buckets).

In order to decide which bucket to place an element in, the container applies the hash function, `Hash`, to the element's key (for sets the key is the whole element, but is referred to as the key so that the same terminology can be used for sets and maps). This returns a value of type `std::size_t`. `std::size_t` has a much greater range of values then the number of buckets, so the container applies another transformation to that value to choose a bucket to place the element in.

容器通过哈希函数 `Hash` 作用于元素的键来确定其所属的桶（对于集合而言，键即元素本身，但为统一集合与映射表的术语仍称作键）。该函数返回 `std::size_t` 类型的值。由于 `std::size_t` 的取值范围远大于桶的数量，容器会对此值进行二次转换以确定元素应存入的桶。

Retrieving the elements for a given key is simple. The same process is applied to the key to find the correct bucket. Then the key is compared with the elements in the bucket to find any elements that match (using the equality predicate `Pred`). If the hash function has worked well the elements will be evenly distributed amongst the buckets so only a small number of elements will need to be examined.

根据指定键检索元素的过程非常简单：首先对键执行相同处理以定位对应桶，随后通过相等性谓词 `Pred` 将键与桶内元素进行比较以寻找匹配项。若哈希函数表现良好，元素将均匀分布于各桶中，此时仅需检查少量元素即可完成检索。

You can see in the diagram that `A` & `D` have been placed in the same bucket. When looking for elements in this bucket up to 2 comparisons are made, making the search slower. This is known as a *collision*. To keep things fast we try to keep collisions to a minimum.

In open-addressing containers, buckets can hold at most one element; if a collision happens (like is the case of `D` in the example), the element uses some other available bucket in the vicinity of the original position. Given this simpler scenario, Boost.Unordered open-addressing containers offer a very limited API for accessing buckets.

As more elements are added to an unordered associative container, the number of collisions will increase causing performance to degrade. To combat this the containers increase the bucket count as elements are inserted. You can also tell the container to change the bucket count (if required) by calling `rehash`.

The standard leaves a lot of freedom to the implementer to decide how the number of buckets is chosen, but it does make some requirements based on the container's _load factor_, the number of elements divided by the number of buckets. Containers also have a _maximum load factor_ which they should try to keep the load factor below.

And even then, the standard doesn't actually require the container to pay much attention to this value. The only time the load factor is _required_ to be less than the maximum is following a call to `rehash`. But most implementations will try to keep the number of elements below the max load factor, and set the maximum load factor to be the same as or close to the hint - unless your hint is unreasonably small or large.
